Hi, guys, help is needed.
I am trying to install Yosemite (14a389) to my HP z800 workstation, which has two Intel Xeon E5520 CPU and 96 GB ram. However, I am stuck at this screen and followed by a black screen (the screen is totally off).

To install it, I have installed only one SSD (tried on both SATA and SAS port, which is recognized by bios) and Nvidia GTX 760.
For install, I used the latest chamelon (on a USB thumb drive) for boot and another SSD for install file disk.
1. -v -f kext-dev-mode=1
2. -v -f kext-dev-mode=1 npci=0x2000
